Application filed- April 17, 1922.1 Serial No. teases.

To all whom it may concern:

'B'e it known that I, GEORGE IVIGGIN Ton, a citizen of the United States, residing at the city and county of Kalamazoo, State of Michigan, have invented certain new and useful Improvements in Binders, of which the following is a specification.

This invention relates to improvements in binders.

My improved binder is designed for the binding 0t sheets permanently and is partic-ul'arly designed by me for the permanent binding of sheets which have been used in.

loose sheet accounting but which it is desired to preserve for permanent record. improved binder may, of'course, be used for the binding; of any sheets, catalogs or the like. V

The main objects of the invention are:

First, to provide an improved binder which is very simple. and economical in its parts and one in whichthe parts maybe quickly assembled with the sheetsto permanently bind and secure them.

Second, to provide an improved binder having these advantages which is very secure, it being quite impossible to release the sheets without substantially destroying the binder or the sheets. 7

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices'and means described the following specification. The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing, forming a part of this application, in which:

' Fig. I is a perspective view of a binder embodying the features of my invention.

Fig. II is a vertical section on a line cor responding to line 2--2 of Fig. I.

Fig. III is adetail horizontal section on a line corresponding to line 3'3 of Fig. II.

Fig. IV is a plan view of one of the sheets partially broken away.

Fig. V is a perspective View of one-of the post clamping members.

Fig; VI is a detail perspective vlew' of one of my improved binders provided with aback. Fig VII is a plan view of the back. F VIII is a detail section on a line. corresponding to line 88' of F IX ofa. slightlyniodified form of my invention, the posts being round instead. of fiatfas shown in the embodiment described.

Fig. IX is a detail section on. a line cor responding to line '99 of Fig. VIII.-

Fig. X is a perspective view 01. the-clutch or clamping member of the embodiment. shown in FigsIVIII and IX. i Fig. XI isa plan view of one of the sheets of Fig. VIII. I

1n the drawing similar reference charac tcrs refer to similar parts throughout the several views and, the sectional views are taken looking in the'd'irection of thelittle' arrows at the. ends of the section lines.

Referring to the drawinggthe sheets 1,

illustrated in IVQare provided with T-shaped slots 2adap-ted. to receive. the binding straps of binders. It. will: be. understood that the shape or the opcningsfis not-ma-. terial. f i i v v My improved binder. comprises a .pair of binding bars 3 hinged to the covers 4 at The binding bars are. provided withpost members 6' arranged in coac ting pairs. to slide upon each other within the sheet body, as is shown in Fig. II, thepost members 6 being flattened to: fit the holes 2 of the sheets 1. These post members are provided with ratchet teeth 7 on their meeting; faces so that .when they are engaged they are held against withdrawal.

To lock the post members in clamping engagement I provide clutch plates Shaving holes 9 therein through which the post members project and provided with spring clutchmembers 10 secured at one end by the rivet 11 and notched at 12to receive one of the post members. clutch. plates 8 are arranged within thcbody of the sheets, preferably centrally thereof, and. when the post members are pushed to gether and the sheets clamped down upon the spring plates 10 these springplates are pressed against the plates. 8v and engagethe posts, clamping them together, so that it is lITlPOSSlblB t0 Withdraw from the, heet,

These clamping or body or to release them without substantially destroying some part of the binder or sheets. The holes 9 are in the form of slots and are of such dimensions that the post members slide freely therethrough but are held laterally and cannot become displaced within the sheet body by twisting and other strains to which the binder may be subjected.

When a back is desired, I provide a back piece 13 of suitable flexible material such as. cloth or leather having holes let near the one end adapted to receive one of the binding posts and holes 15 near the otherend adapted to receive the other, the holes 1 5 being of such dimensions as to permit of considerable adjustment of the back strip to adjust it for variations in the number of sheets. This back strip is drawn to position before the top binding bar is pushed completely home, as it is impossible to adjust it after this is done.

In the modification shown in Figs. VIII and IX the sheets 16 have round holes 17, while the post members 18 are of semi-circular cross section to fit these holes.

My improved binder is very economical in its parts and may be quickly adjusted to a body of sheets and when adjusted thereto the sheets are bound so that none of them can be freed without such manipulation as would substantially destroy some 'part of the binder or the sheets.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. The combination in a binder for sheets slotted to receive binding posts, of binding bars, complementary fiat binding post members mounted on said bars to be slidably engaged in said holes in said sheets edge to edge and having coacting teeth on their meeting edges, a clutch plate adapted to be interposed between sheets of the sheet body and provided with a'slot-like hole through which both of said post members project and by which they are supported edge to edge, and a spring clutch member mounted on said plate in diverging relation to and positioned so that when collapsed upon the clutch plate its said slot is partially closed and the said post members are clamped between the cllugch member and the opposed end of the s o 2. The combination in a binder for sheets perforated to receive binding posts, of binding bars, binding post members mounted on said bars in coacting pairs for slidable engagement within the holes of the sheets and having coacting teeth on their meeting faces, a clutch plate adapted to be interposed between sheets of said sheet body and provided with a hole through which said post members project, and a spring clutch member mounted on said plate to normally project therefrom and positioned so that when collapsed upon the plate its said perforation is partially closed and the post members are clamped together with their teeth in engagement. V

3. The combination in a binder for sheets perforated to receive binding posts, of binding bars, binding post members mounted on said bars in coacting pairs for slidable engagement within the sheet body and having coacting teeth on their meeting faces, a clutch .means interposed between sheets of said sheet body comprising a clutch plate having a hole therein adapted to receive the post members, and a clutch member mounted on said plate in diverging relation to and positioned so that the perforation in said clutch plateis partially closed when the clutch member is collapsed thereon, thereby clamping the post members with their teeth in engagement whereby the clutch is actuated by compress ing the sheets thereon.

4-. In a binder, the combination with the sheets having holes therein adapted to receive binding posts, binding bars, post members arranged on said binding bars in coacting pairs for slidable engagement within the sheet body and having teeth on their meeting faces, and a clamping means adapted to be disposed between sheets of the sheet body and actuated by the pressure of the sheets thereon to clamp the post members together. V e 5. The combination in a binder for sheets perforated to receive binding posts, coacting pairs of post members adapted for slidable engagement within the sheet body when introduced from opposite sides thereof, said post members having coacting teeth on their meeting edges, and a clutch means adapted to be disposed between sheets to be bound and actuated by compressing the sheets thereon to clamp said post members together with their teeth in interlocking engagement.

6/ The combination in a binder for sheets, of a enacting-pair of post members adapted for, slidable engagement within the sheet body when introduced into the body of sheets from opposite sides thereof, a clutch plate adapted to be interposed between sheets of said sheet body and provided with a hole through which said post members project, and a spring clutch member mounted on said plate in diverging relation thereto and positioned so that when collapsedupon the plate said post members are clamped together.

7. The combination in a binder for sheets, of a coacting pair of post members adapted to telescope within the sheet body when introduced from opposite sides thereof, a clutch plate adapted to be interposed between sheets of the sheet body and provided with a hole through which the telescoping ends of said post members project, and a clutch member mounted on said plate in diverging relation thereto and positioned so that when collapsed upon the clutch plate its said hole is partially closed and said post members are clamped between the clutch member and the opposite edge of the hole.

8. The combination in a binder for sheets, of complementary post members adapted to be introduced into the body of sheets from opposite sides thereof, a clamping means disposed between sheets of the said body comprising .a clutch plate having a hole therein through which the said post members are disposed, and a clutch member mounted on said plate in diverging relation to and positioned so that the hole in said clutch plate is partially closed when the clutch member is collapsed upon the clutch plate, thereby clamping the post members between the clutch member and the opposed edge of the hole. I

9. The combination in a binder for sheets, of a post, a clutch plate adapted to be interposed between sheets of the sheet body to be bound and provided with a hole through which said post extends, and a spring clutch member mounted on said plate in diverging relation thereto and positioned so that when collapsed upon the clutch plate its said hole is partially closed and said post is clamped between the clutch member and the opposite edge of the hole. 7

10. The combination in abinder sheets perforated to receive abinding post, of apost adapted to be inserted in said perforations, a post clamping means adapted to be interposed between sheets of said sheet body comprising a clutch plate provided with a hole through which the post is disposed, and a clutch member movably mounted on said plate in diverging relation theretoand positioned so that when 001- for o lapsed upon the plate its said hole is partially closed and the post is clamped between the clutch member and the opposed edge of the hole.
